BURR AND SHIVE EXTRACTOR FOR CARDING -MACHINES'.

SPECIFICATION forming part of Letters Patent No. 495,413, dated April 11, 1893. Application filed March 17, 1892. Serial No. 425,841. (N model.)

To all whom it may concern:

Be it known that we, ANDREW HOWARTH and FRANCIS A. HOWARTH, both of Oxford,

- in the countyof l/Vorcester and State of Massainvention belongs to make and use the same,

the strippers; E, the workers,

reference being had to the accompanying drawings and the letters marked thereon, forming a part of this specification, and in which Figure 1.1epresents a vertical section of so much of a carding machine as is necessary to illustrate our said invention. Fig. 2- represents a top or plan view of a portion of the carding machine shown in Fig. 1, as will be hereinafter described. Fig. 3- represents a cross section on line 3, 3, Fig. 4, looking in direction indicated by the arrow, same figure,scale enlarged. Fig. 4- represents a side view of a part of this machine, as will be hereinafter described,-same scale as Fig. 3. Fig. 5- represents upon the same enlarged scalea side view of a part, together with a sectional view on line 5, 5, Fig. 3-arrow indicates direction. Fig. 6 shows a section on line 6, 6, Fig. 1, lookingin direction indicated by arrow.

7 By our present invention many of the most serious objections to devices desired to accomplish similar results are overcome and obviated, and that too in a very simple and convenient manner.

In the drawings, Figs. 3, 4, 5 and 6 are drawn to an enlarged scale to aid more fully illustrating our improvements.

In the drawings, the part marked A, indicates the frame; B, the cylinder; at. a, the feed rolls; 0, licker-in; D, the tumbler; E, and E the burr roll, and all these parts may be of the usual and well knownforms of construction.

We will now describe one good and practical way of making and using our improvements in carding machines whereby burrs, shives and other vegetable matters are very efiectually removed from the wool or stock in the operating of carding, and which improvements are designed for and adapted to be quickly adjusted to the variety of stock to be manufactured into cloth.

In the drawings the part marked F,is a sector frame and is fastened to the inside of the frame A, by bolts f, f, which pass through its earsf',f, and securely hold said sector frame F, with its slot f made in the are of a circleequidistant from the axis of motion of the tumbler D. One of these sector frames F, is fastened under each end of the journal of tumbler D,-one being clearly shown in Figs. 1 and 2 of the drawings, and are provided in this instance, each with three bearing or'supporting pieces G, held to their respective sector frames F, by boltsf, which pass through the respective holes 9 in supporting pieces G, and slots f, in frames F, the latter being recessed on their outer sides on each side of slots f, as seen at f, and into which recesses the heads of bolts 1, fit loosely, but are prevented from turning when their nuts f are turned up to fasten the supporting pieces G, to their frames F, in the desired positions for use, as hereainfter fully explained. It will be seen that bolts f, are only adjustable laterally in the slots f in the sector frames F, and

therefore the supporting frames G, have only two modes of adjustment, viz., they can be swung or turned to the right or left on their bolts f, when nuts f, are loosened, and also movedilaterally when their boltsj' are moved in the curved slots f in the sector frames F. The upper portions of supporting pieces G, are made to project inward from the ear parts 9 and are slotted or cored out to form slots or recesses to receive the ends of the comb bars H, to which are fastened the steel combs I-l', havingteeth on their upper edges as clearly shown in the drawings. Combs H, are fastened, if desired to the comb bars H, in this instance by screws h,the barsbein g recessed out to receive the combs as indicated in Fig. 3, so that the bar and comb will be of the same thickness as the lower part of the comb bar H, which just fills the slot g in the comb bar supporting piece or frame G. Said slot 9 is of sufficient depth to receive the comb-bar 11 so fully that the lower edge of the comb will be also inclosed in the slot-especially when the comb is newand has not as yet been much worn 05. It is important that the comb be adapted to delicate adjustment to meet the requirements of different stock, and also the grinding off of the tumbler teeth, as well as the wearing of the comb teeth. Either end of the comb bar H, can be adjusted up or down by means of the adjusting screws g, and when so adjusted can be securely held in such adjusted position by turning in the comb bar holding screws g ,screws 9', pass up through the under portions of supporting pieces G, and act upon the lower edge of the comb bar H, as it rests in the recesses g, while screws 9 by their gravity pass through the side of supporting piece G at the back of the comb bar and press against the comb bar H, so as to clamp the comb H strongly against the opposite wall of the slot 9: hence the screws h are not absolutely necessary when the comb is new or wide. By this combination of devices the teeth of the combH, can be set in verynicely adjusted positions in relation to the ends of the teeth on the tumbler D.

In Fig. 1, three combs H, with their supporting, holding and adjusting mechanism are thrown arranged in position to, work in combination with the tumbler D, to remove the shives and burrs from the wool as it passes from the licker-in to the tumbler and from that to the carding cylinder B, and which are not displaced and detached by the burr roll E As the tumbler D, revolves the shives, burrs and other vegetable substances are arrested by the teeth of the combs H separated from the wool stock, and thrown off,and drop or fall on the floor below or into a proper receptacle provided for that purpose. If the burrs and shives are not removed before the stock is Worked into cloth the value of the cloth is greatly lessened unless much time is expended in removing the burrs and shives by hand labor, which is slow and expensive.

Our improvementsenable the operator to quickly adjust the comb. or combs to act in the most effectual manner in combination with the tumbler teeth in detaching and knocking off the burrs, shives and other objectionable matter.

Diiferent stock requires the comb or combs to be differently adjusted. In some stock the burrs and shives will be partially detached by the first comb, adjusted for that purpose, and the operation completed by the next comb or combs. In some cases the combs will not all be pointing to the center of the tumbler, but one or more may be turned to the right or left of such a position, and our improvements enable the operator to nicely adjust the combs as may be desired, and that too in a little time.

each side bar of each side bar of said Our improvements may be employed, in part, in the Groves machine, patented August ll, 1891, in which case the combs would be adjustable, as in our machine. v

What we claim, and desire to secure by Letters Patent, is

1. In a carding machine, the combination with the main frame, and the tumbler-roll; of a sector-frame secured to the inner face of said main frame and having a longitudinal slot struck 'on anarc around the axis of said roll, the outer face of said sec+ tor-frame being recessed each side of the slot, a comb, a bar to which the comb is attached, a supporting piece for each end of the bar, said piece having a vertical, perforated ear, and a bolt whose head rests in said recess, whose shank passes through the-slot and perforation, and whose nut bears; against the inner face of'said ear, all as and for the purpose set forth.

2. In a carding machine,th e combination with the main frame, and the tumbler-roll; of a sector-frame secured to the inner face of v main frame and having a longitudinal slot struck on an are around the axis of said roll, the outer face of said sector-frame being recessed each side of the slot, a comb, abar to which the comb is attached, a supporting piece for each end of the bar, said piece having a vertical, perforated ear,a bolt whose head rests in said recess, whose shank passes through the slot and perforation, and whose nut bears against the inner face of said ear, said piece further having an upright recess in its body and within which the end of the comb-bar rests by gravity, and an adj ustin g screw passing upwardthrough the bottom and a holding screw passing laterally through the side of said recess against the comb-bar, as and for the purpose set forth.

3. In a carding machine, the combination with the main frame, and the tumbler-roll; of I a comb, a bar having a recess in its face in which the comb is seated, a supporting piece for each end of the bar, said piece having an upright slot in its body into which the end of the comb-bar and lower edge of the comb are seated, an adjusting screw passing upward through the bottom and a holding screw passing laterally through the sidewall of saidslot against the back of the comb-bar, said piece further having anear, and means foradjustably connecting the ear with said frame, as and for the purpose set forth.
